this vertical adjustment 'clamp screw' is i provided which is carried in a slot 19 in the end wall of the case 11. Aft-er the desired adjustment has been obtained, clamp screw 18 is tightened and furnishes a permanent holding meansfor the bearing block 12. By

V'referring to the drawingsV it will be seen f of bearing blocks 12.

that there are duplicate bearing blocks 12 and corresponding adjustments on both sides of each of the sides of the upper roll. Shafts 14 are provided with end-thrust collars which abut against the inner sides v Bushings 21 and shafts 15 support the heating elements in 'two of thejrolls. Thetwo upper rolls ld are adjustably supported 'as described; it is not Anecessary that the two lower rolls l?. be adjustably supported,A so accordingly they are mounted in bearings which are the same as vthose before described except that the bearing blocks'12a are in this case fixed with reference to the case 11, preferably integral lwith the case.r i

It will be noted from the drawings that one roll of each pair is provided with heating means and that this is preferablythe `upper roll of one pair and the lower roll of the other pair. By this arrangement I give i a bill two successive ironings and beatings,

with heat applied directly to both sides of the bill` and at the same time use only two heating elements. The two rolls that have the heating means have their shafts 14 hollowy to carry bushings 21 and shafts 15 to support the heating elements; and although it is not necessary I have shown the other two rolls similarly equipped and the shafts l5 and bushings 21 in place, so that the onthe side wall of the case.

Ione central shaft 23 but they may however,

be driven in any suitable manner. I have shown the shaft as passing through the ma.- chine and supportedin bearings 24: formed j One end of this shaft passes bevond lthe side. wall and connects to a suitable coupling 25. which i Vcoupling is connected to the shaft of a typical motor 26 from which the power is -derived. 1t will be readily understood that "are driven in pairs and inf opposite diree-l the machine may be driven in any suitable manner and 1s not in any way limited to lthis particular type of driving means.

As will be noted in Figs. 2 and 4 the rolls "tionspso that the bills may be fed intovthe machine and the first pair of rolls will then feed ythe bill into the next successive pair, `which then passes it outward and lbeyond the case. To permit feeding the bills into the machine and then gathering them after be* ing treated, two slots or openings are arranged in the case 11. The entrance opening is provided with ay substantially flat bot- Atorn 27 formed as a part of case 11 and eX- tending out from the case far enough to allow several bills to be `stacked ready to be inserted in the machine. This shelf or holder may be provided with suitable side plates 28. Bottom 27 passes within the case 11 and extends right up to the first pair of rolls to prevent the bills from falling before they engage the lower roll. A curved projection 29 extends inwardly and guides the bills into the first pair of rolls. Back of the last pair of rolls are somewhat similar projections. The upper projection 30j however, is made adjustable so that the distance between itself and the lower shelf 27a may be Ayaried. This adjustment is obtained by means' of screws 31 which are carried in slots formed in a side wall of the case, and are screw threadedly engaged to the projection 30. The outward extending portion of the lower projection 27a is somewhat shorter than that of the extending shelf 27. Guide plates 32 are arranged aboveand below the line of movement of the bills. These plates are held concentric with shafts 14C by supporting portions 33 which loosely lit these shafts at the ends of the rolls. Plates 32 are secured to-portions 33 bymeans of screws 32a. These plates are arranged so as to eX- tend between the rolls and parallel to the axis ofthe rolls, and to fit loosely but snugly between the upper rolls and likewise with the lower rollsj There are two of these plates 32, one between the lower rolls R and one between the upper rolls R. This feature prevents the bills from tending to cling to the rolls and revolve with them.

It is preferred. for mechanical conveniences, that each pair of rolls be driven at the opposite end to that which the other pair is driven. Upon shafts 14 are gears 34 which mesh with each other and cause the lower shaft to drive the upper shaft in each pair. Near gear 34 and upon the lower .shaft 14 of each pairis a slightly larger gear 35 which meshes with pinion 36 secured to drive shaft 23. All the upper and lower rolls are thus driven in the proper direction to feed the bills through the machine. It is preferred that the bills be fed;

through the machine lengthwise, and this aids in feeding the bills through the rolls, in that the maximum lengt-h assures one pair or both pairs of rolls constantly pulling the bills forward. Y

As was statedhereinhefore. at least one upper and one lower roll is to be heated io directly heat both faces of the bills,` and 1 prefer to heat the upper roll of one pair and the lower roll of the other pair so that the.

aannam Y bills iyill be heated simultaneously with .each

pressinn TheV heatingmeans are supported fensha tsyl, which are stationary. These lshafts lare provided at each end Vwith bush- ',ings 2,15 around which hollow shafts l4.ro tate.
